The second example is transparent p-type semiconductors. Employing chalcogen orbitals and layered crystal structures, large hole mobilities, degenerate p-type conduction, and room-temperature stable excitions are rendered in wide bangap materials. Room-temperature operation of excitonic blue light-emitting...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
